Hemostasis device for cardiovascular nursing puncture

Abstract

The invention discloses a hemostasis device for cardiovascular nursing puncture, and relates to the technical field of puncture devices. The device comprises a length-adjustable binding belt; the mounting cylinder comprises an upper cylinder body and a lower cylinder body which are coaxially arranged; the upper end of the upper cylinder is closed, a mounting hole is formed in the center of the closed end, the lower cylinder is slidably connected to the lower end of the upper cylinder in a sleeving mode in the axial direction, and two connecting buckles are symmetrically installed on the two sides of the outer side wall of the lower cylinder. The lifting driving assembly is fixed to the outer wall of the lower barrel, and the lifting end of the lifting driving assembly is in transmission connection with the upper barrel; the pressing air bag is a corrugated pipe type air bag with two closed ends. The air bag is used for hemostasis through compression, the pressure adjusting precision is high, the comfort of a patient can be improved, when the pressing air bag leaks and retracts, the lifting driving assembly is used for enabling the upper cylinder to move downwards, the contracted pressing air bag is driven to move downwards, the pressing pad continues to make contact with a puncture part, mechanical pressure is provided, and compression hemostasis continues; potential safety hazards caused by incapability of stopping bleeding in time when the air bag leaks are prevented.
